Ai Haibara timeline

Plot overview

Older Brother Kidnapping Case (Manga: 176-178, Anime: 129)

First Haibara's "evil" appearance.

Conan's class receives a new student named Ai Haibara. She acts rather cold and reserved when the Detective Boys try to befriend her, and Genta notices she's looking at Conan suspiciously. She tells them where she lives but Conan fails to realize it's at Agasa's home (Tokyo blocks are not numbered in sequential order and Conan has never had reason to learn Agasa's mailing address due to their being neighbors).

After school, a boy named Toshiya asks the Detective Boys to find his missing brother. The Detective Boys along with Haibara investigate Toshiya's house and finds a painting of Natsume Sōseki. Toshiya reveals that before his brother disappeared, a woman, who had an interest in that portrait, approached Toshiya's brother. The Detective Boys search around town to ask whether anyone has seen the woman or Toshiya's brother. Conan notices that a man was using a counterfeit ¥1000 and realizes Toshiya's brother was actually kidnapped and forced to help create counterfeit bills. After following the man along with the clues Toshiya's brother left behind, they are able to apprehend the organized crime group and save Toshiya's brother.

University Professor Murder Case (Manga: 179-181, Anime: 129)

Haibara cries on Conan after asking him why hadn't he helped her sister.

On the way home, Haibara reveals to Conan that she is a former member of the Black Organization, with the code name "Sherry". It is further revealed that she has actually betrayed the group and escaped with the use of the APTX 4869, which caused her to become a child. She reveals that she once accidentally sent a floppy disk containing data on the Black Organization to her older sister, and the disc is now in the possession of her sister's professor, Masami Hirota.

Agasa takes Conan and Haibara there to retrieve the disk, only to discover that Hirota has been murdered. The suspects are Hirota's three students who visited that day. Conan reveals the culprit to be a man named Akira Shirakura; Shirakura after bludgeoning Hirota to death and tied the answering machine cassette tape around the key to the room which rewound when a call was made, subsequently dragging the key into the room. As evidence, Conan reveals that Shirakura's fingerprints should be found on the tape. After seeing Conan's amazing display of logic after she had given up on the case herself, Haibara breaks down and asks Conan why he could not save her sister, Akemi, from the Black Organization. Conan finally makes the connection that the "Masami Hirota" who Gin killed was actually Shiho's sister and sympathy for Haibara's attitude stirs in him. The disc is taken into police custody, but once it is released to them Haibara attempts to read the files off the disk—only to have a virus delete all the data.

Stadium Bomber Case (Manga: 189-191, Anime: 130-131)

Haibara is hesitant to see the football match closer (fearing that her face will be visible on TV). After, she tells Conan that she's 18 years old.

Blue Castle Treasure Case (Manga: 200-203, Anime: 136-137)

Haibara talks to Ayumi, saying that she doesn't have love interest in Conan so Ayumi doesn't have to worry about her.

Movie Theater Case (Manga: 222-224, Anime: 138-139)

At the start of the second Gomera movie, Ayumi falls asleep and puts her head on Conan's shoulder. When Conan turns to Haibara, saying he needs to use the restroom and asks her if she would switch seats, she has also put her head on Conan's shoulder, having fallen asleep as well.

Innocent Suspect Case (Manga: 231 and 232-233, Anime: 156-157)

The episode opens with Haibara and Conan in what looks to be an abandoned and empty room. Haibara tells him that she (possibly referring to Ran) has found out about his identity. When he asks her why she's telling him all this, she tells him that he can see into the hearts of the wicked, but he couldn't understand a woman's heart, then tells him that she's been in love with him since she met him. We see Conan's face, but it doesn't appear to be at all surprised, and Haibara continues with: "I guess you didn't even notice... Kamen Yaiba-san." After Mitsuhiko yells out "CUT!", it is revealed that both Conan and Haibara were merely acting, and practicing lines for Teitan Elementary School's play, with Mitsuhiko as the director.

Reunion with the Black Organization (Manga: 238-242, Anime: 176-178)

Shiho shot by Gin.

In Episode 176-178, Conan encounters Gin and Vodka again. Haibara is kidnapped and confined in a wine cellar by the Black Organization member Pisco, but she escapes before Gin and Vodka arrive by drinking baijiu to turn back into an adult. Gin anticipates her actions and intercepts her on the roof. He shoots selectively to wound her, intending to force her to explain how she escaped from the Organization before he finally kills her. Conan prevents Gin from killing her by shooting the man with his tranquilizer wristwatch. Conan tells Haibara to jump into the chimney when a distracted Vodka shoots at him but as he's behind a door, he gets away once Haibara has gone down the chimney. Gin purposely shoots himself in the arm to stay awake. Inside the wine cellar, Pisco is about to kill Haibara but Conan rescues her after tricking Pisco into accidentally causing a fire. They make their escape as Pisco tries to find them amidst the fire and smoke. At this point, Gin crawls from the chimney and confronts Pisco, citing his failure to remain in the shadows in his mission and kills him before Pisco is able to tell him the truth that Shiho Miyano has deaged into a young girl. Worried that the Organization is after her, Haibara decides to leave the city. Conan anticipates that Gin will predict her next move as leaving Tokyo so it will be better if she does the unexpected and remains in Beika. Unknown to Conan or Haibara, Vermouth saw Haibara at the party and uses her expert disguise skills to get closer to Haibara and Conan in order to confirm Haibara's identity as Sherry and then kill her.

Dangerous Cave Case (Manga: 251-254, Anime 188-189)

Conan finds out that Ran suspects him of being Shinichi, because Ran said she knew Conan's blood type for a blood transfusion, which Haibara hears.

School Play Case (Manga: 255-257, Anime: 190-191)

Haibara's about to shoot Conan.

While Conan is in the hospital contemplating admitting his identity to her, Haibara enters and points a gun at his head, saying that the Black Organization has found out about her due to an unknown agent being present at the Pisco incident. Because of this, Professor Agasa is held hostage and, in exchange for his life and a chance to return to the Black Organization, Haibara is required to terminate all the links she had in her child identity. However, when she pulls the trigger a bunch of flowers come out, showing that the story was just an act. Still, she uses this story as her point: both Haibara and Conan cannot reveal their identities no matter the situation, in order to prevent such a tragedy from occurring.

During that night, Haibara explains her plan to disassociate Conan from Shinichi in Ran's eyes. She has Conan take a prototype antidote for APTX 4869 and then disguises herself as Conan. For the rest of the arc, Conan returns as Shinichi while Haibara is present as Conan, thus creating the illusion of Shinichi and Conan existing at the same time, disproving that the two are the same person.

Elevator Murder Case (Manga: 258-260, Anime: 192-193)

At the end of the Desperate Revival arc, the antidote begins to run out and Shinichi runs into the bathroom, where Haibara is still disguised as Conan already waiting for him. She knows that Shinichi would run into the men´s bathroom after the symptoms of the regress conversion start to appear. Presumably, she leaves Conan's clothes for Shinichi and changes back into Haibara before leaving with Agasa who's waiting for her in the car park. Returned to the form of Conan once more, Conan returns to where Ran is waiting for Shinichi and tells her Shinichi has to leave urgently on another case.

Music Box Case (Manga: 261, Anime: 194)

Some time after the "comeback of Shinichi", Conan asks Haibara for some more antidotes, as he would like to meet Ran again in his adult form to tell her the whole truth. Haibara refuses and says it's too late, and it could be dangerous for Conan to swallow another prototype that could kill him. Haibara and the Detective Boys seem delighted to see Conan again, though the Boys are completely ignorant of who Conan really is.

Mermaid's Curse Case (Manga: 281, Anime: 223)

During the investigation of a case involving a lottery, Heiji Hattori and Conan goes through books with names of contestants from previous lotteries. Conan finds the name Shiho Miyano in one of the books and recalls it as the real name of Haibara. But he can't imagine that it's the same person, since she doesn't appear as a person desiring eternal youth and beauty.

Bus Hijacking Case (Manga: 287-289, Anime: 230-231

Haibara in pinch.

Vermouth, disguised as Tomoaki Araide, boards a bus that Haibara, Agasa, and the Detective Boys are riding to a ski resort. Whatever plan Vermouth might have had is completely interrupted by the bus being hijacked by random criminals and the presence of two FBI agents that have been tracking her: Jodie Starling and Shuichi Akai. Haibara detects Vermouth's presence on the bus. She becomes so afraid that the Detective Boys, Conan, and Agasa will be killed because of her that she decides to commit suicide, deliberately staying behind in the bus which is about to explode. Realising her intent, Conan runs back and with his quick thinking, saves her. He asks her not to run away from life. However, the event caused her to remain anxious for several days.

Dog Lovers Case (Manga: 290-292, Anime: 233-234)

The hijacked bus incident in The Mysterious Passenger Case led Haibara to be especially worried about her situation. Ayumi, Genta, and Mitsuhiko attempt to cheer her up and, with the help of Arthur the dog, manage to make her smile. Conan comments that she should keep that expression, since it makes her look like a child, causing Haibara to blush.

Netted Man Murder Case (Manga: 311-313, Anime: 246-247)

While she is at the beach with the Detective Boys and Ran, Haibara once again witnesses Conan's/Shinichi's feelings for Ran. She remains in the water until Ran notices she got a sunstroke. Conan wonders why she did not stay with Professor Agasa, and she answers that she did not want to run away from a dolphin (Ran) who is loved by the ocean (Shinichi/Conan), and a shark (herself) that ran away from the cold and dark bottom of the ocean cannot compete with the dolphin. However, Conan fails to understand this metaphor, which draws a parallel between Ran and Haibara.

Bathroom Murder Case (Manga: 423-425, Anime: 340-341)

Haibara, with the help of Conan, fins recording tapes from her mother. She's happy and relaxed to hear her mother's voice

Halloween Party Case (Manga: 429-434, Anime: 345)

Ran covering Haibara from getting shot.

Vermouth finally launches her plan to kill Shiho. She prepares a distraction to lure Conan away so that Haibara is alone at Agasa's. Taking advantage of the fact that Haibara has practically become ill from fear, she calls as Dr. Araide to tell Haibara she is taking her to the hospital because she has been unwell for so long. The eavesdropping FBI agent Jodie Starling arrives first to protect Haibara and starts driving her towards the shipping yard where the FBI have laid a trap for Vermouth.

In a complicated turn of events, Vermouth reveals she already thwarted Jodie's trap, and then shoots her. Haibara then reveals herself to be Conan; Yukiko had helped with his disguise while Conan sent Heiji Hattori to participate in Vermouth's distraction. The real Haibara then shows up which distracts Conan long enough for Vermouth to dart him with his own stun-gun watch. Just as Haibara is about to be killed, Ran, who had suspected Jodie of being untrustworthy and decided to spy on her, jumps from Jodie's car trunk and protects Haibara. Vermouth is unwilling to kill either Conan or Ran because they had saved her life in the past. Part of the reason why she originally did not tell the rest of the Black Organization about Haibara's true identity is likely because they would find out about Conan too and then silence him and everyone around him as well.

Before Vermouth can come up with another plan, the other FBI agent, Shuichi Akai arrives and forces Vermouth to flee with Conan as a hostage. Vermouth dials the boss of the Black Organization to lie to him about why she was injured. After the call she checks Conan and found he's wired to a recorder after cutting open his shirt. As she is about to destroy it, he wakes up from his pretended snooze and tells her his associate will arrive if the recorder is destroyed. He threatens to give the recorder to the police for analysis unless Vermouth promises that she will give up on trying to kill Haibara. Vermouth consents and unexpectedly releases a sleeping gas. When Conan wakes up, he found Vermouth had considerately covered him with her coat but there is no sign of her in the car except for a bloody patch on the seat. He realises she had destroyed the recorder and then shot herself from succumbing to the gas. A wounded Vermouth makes her way to a phone booth and calls for a pickup from her associates.

Kaitou Kid and the Three Instruments (Manga: 475-478, Anime: 394-396)

Conan figures out the boss's full number, but Haibara warns him not to call it because it is "Pandora's Box". Conan then thinks he can get Detective Takagi to figure out who the number belongs to, but then Haibara warns that if he does, Detective Takagi will be killed. This scene is the first time Haibara openly reveals to Conan that she has been hiding important secrets about the Black Organization from him; earlier she had lied to him. The exchange suggests that Haibara is withholding information because she fears Conan will make a rash move.

Red, White, and Yellow Case (Manga: 622-624, Anime: 509)

Haibara does not like Subaru.

Not long after Akai's death, Conan hears fresh intel from the FBI that a new Black Organization agent called Bourbon is looking for Shiho, which Conan keeps secret from Haibara. As Conan and Haibara investigate a normal case, Haibara feels that an organization member is around. The organization member which she felt is implied to be one of the innocent suspects, Subaru Okiya. Conan invites Okiya to live in Kudo's house since Okiya's apartment was burnt to the ground. Okiya appears in other cases later on, including at the Haido mall where the rest of the Black Organization gathered to chase a rumored sighting of a scarred Shuichi Akai. Although Okiya is trusted by Conan and Agasa and behaves kindly to Haibara, she remains frightened of him. Later, some of his actions lead her to believe he might be someone she knows and she comes to trust him more, even attempting to uncover his identity when she thought he was asleep.

Shadow Approaching Haibara's Secret (Manga: 815-817, Anime: 699-704)

Haibara turns into Shiho via the prototype antidote for the first time.

Haibara is forced to revert to Shiho using a temporary antidote to save the other children of the group from a fire. A video of her as an adult is sent to the Mouri Detective Agency by Mitsuhiko which Sera, Okiya, and Amuro find out about. Because of this, Haibara is later targeted by a plot concocted by Vermouth and Bourbon aboard the Bell Tree Express Train. Bourbon is revealed to be Amuro and Haibara learns that he knew her parents. Bourbon was hoping to capture Shiho alive, but Vermouth's modifications to his plan which were designed to kill her led to Shiho supposedly being blown up on the train. However, the Shiho Vermouth and Bourbon thought they killed was really Kaitou Kid in disguise, after Conan forced him into the plan. Because of this, all of the Black Organization besides Vermouth think Shiho is now dead, and Vermouth decides to keep it to herself

The Heartfelt Strap (Manga: 997-999, Anime: 925-926)

Haibara refuse to give Conan a couple antidotes in order to go to the Kyoto trip with Ran. Suddenly, she finds out she lost the Higo puppet phone strap she bought at the stadium store. It was particularly precious to her because Ryusuke Higo touched it in the bleachers during the football match. She freezes in disbelief and collapses against the wall. Conan decides to go with the Detective Boys to find her phone strap, in exchange for the antidotes. In the end, they are able to return the strap but it was partially destroyed. At first, Haibara still refuses Conan's pleas to give him the antidote but in the end, she gives him the antidote later on after his hard work for finding the strap.

TV Drama Filming Site Murder Case (Manga: 1025, Anime: 995)

Haibara mentions her father worked as a member of Shirohato Pharmaceuticals R&D team thirty years ago. However, the company went bankrupt twenty-five years ago and her parents decided to open a small clinic.

Akemi Miyano's Time Capsule (Manga: 1070-1072, Anime: 1093-1094)

Haibara finds out her sister Akemi attended Teitan Elementary School and graduated from it nineteen years ago. She also finds out that her sister buried a time capsule at the school as well, which revealed a photo of Akemi and Shiho in the past with a letter on the back. Suddenly, someone heavily triggers Haibara's anxiety, causing Conan to rush outside the classroom. When he asked an upperclassman if any suspicious person passed by, he was informed that only pizza and sushi deliveries came. Conan then dismisses his suspicion and concludes that Haibara must have been overreacting.
